I like how much power I have when cruising on level ground, but starting from stop is a bit tough, would like to improve that a bit. Using Sheldon's calculator is really helpful, thanks again!
You are welcome, glad it is helpful. A lot of people will use a smaller chain ring for the front. I generally will use a 46. Then after you've done that you can monkey around with the rear cog size. Freewheels are available in a variety of sizes, but good ones are spendy so going from one to another to another is prohibitive. White Industries is top-notch. Good pawl engagement.

I agree with the post about the cranks. I don't think the added leverage is going to help much. Also, if you ever choose to go fixed, longer cranks on a bike with a relatively low bottom bracket is potentially dangerous going around corners.
